Abstract
A user-wearable patch pump system for delivery of insulin or other medicament can include a patch pump having a reusable drive unit and a replaceable and refillable cartridge. The cartridge can selectively attach to and be detached from the drive unit. The cartridge can initially be inserted onto the drive unit in a first orientation at an angle to the drive unit and then be rotated to align the cartridge with the drive unit and lock the cartridge in place on the drive unit to form the patch pump.
Core Innovation
The invention relates to an ambulatory infusion pump system that includes an ambulatory infusion pump with a rechargeable battery and an inductive charging device. The inductive charging device includes an upper charging surface configured to inductively charge the rechargeable battery when the ambulatory infusion pump is placed on the upper charging surface and the inductive charging device is connected to a power source.
The system further includes a removable cover that is selectively attachable to the inductive charging device. The removable cover includes an opening configured to receive the ambulatory infusion pump to enable the ambulatory infusion pump to be in contact with the upper charging surface, and the opening has a perimeter shape generally matching a perimeter shape of the ambulatory infusion pump.
In further embodiments, the removable cover conforms to the outer perimeter of the ambulatory infusion pump to aid in retaining the ambulatory infusion pump on the upper charging surface while the ambulatory infusion pump is charging. In some embodiments, the inductive charging device automatically initiates charging when the ambulatory infusion pump is inserted into the opening while the inductive charging device is connected to a power source.
Claims Coverage
The provided independent claims cover three inventive features centered on inductive charging of an ambulatory infusion pump with a selectively attachable removable cover.
Inductive charging with upper charging surface and removable cover opening
An ambulatory infusion pump including a rechargeable battery; an inductive charging device including an upper charging surface configured to inductively charge the rechargeable battery when the ambulatory infusion pump is placed on the upper charging surface and the inductive charging device is connected to a power source; and a removable cover selectively attachable to the inductive charging device, the removable cover including an opening configured to receive the ambulatory infusion pump to enable the ambulatory infusion pump to be in contact with the upper charging surface.
Removable cover opening configured to ensure alignment with generally matching perimeter shape
An ambulatory infusion pump including a rechargeable battery; an inductive charging device including an upper charging surface configured to inductively charge the rechargeable battery when the ambulatory infusion pump is placed on the upper charging surface and the inductive charging device is connected to a power source; and a removable cover selectively attachable to the inductive charging device, the removable cover including an opening configured to receive and position the ambulatory infusion pump on the upper charging surface to ensure proper alignment, where the opening has a perimeter shape generally matching a perimeter shape of the ambulatory infusion pump.
Removable cover conforming to outer perimeter to aid retention while charging
An ambulatory infusion pump including a rechargeable battery; an inductive charging device having an upper charging surface configured to inductively charge the rechargeable battery when the ambulatory infusion pump is placed on the upper charging surface and the inductive charging device is connected to a power source; and a removable cover selectively attachable to the inductive charging device, wherein at least a portion of the removable cover conforms to an outer perimeter of the ambulatory infusion pump to aid in retaining the ambulatory infusion pump on the upper charging surface while the ambulatory infusion pump is charging.
The claims cover inductive charging of a rechargeable ambulatory infusion pump via an upper charging surface while using a selectively attachable removable cover. The cover opening is configured to receive, position, and align the pump, and in an embodiment conforms to the pump’s outer perimeter to aid retention during charging.
Stated Advantages
Enables inductive charging of the rechargeable battery by placing the ambulatory infusion pump on the upper charging surface while the charging device is connected to a power source.
Provides proper alignment of the ambulatory infusion pump on the inductive charging device using the cover opening.
Aids in retaining the ambulatory infusion pump on the upper charging surface of the inductive charging device while the ambulatory infusion pump is charging.
Avoids use of an external port configured to be connected to a power source on the ambulatory infusion pump.
Documented Applications
Charging an ambulatory infusion pump system that includes an ambulatory infusion pump with a rechargeable battery using an inductive charging device.
